Hi,
I only checked DSDT.
The decoded _PRWs tell us:
EHC1 (GPE0D S3)
EHC2 (GPE0D S3)
XHC_ (GPE0D S3)
HDEF WKMD=1(GPE0D S0) WKMD=0(GPE0D S0)
WLAN (GPE09 S0)
RP01 PMEE=1(GPE09 S0) PMEE=0(GPE09 S0)
RMSC (GPE09 S0)
RP02 PMEE=1(GPE09 S0) PMEE=0(GPE09 S0)
RLAN (GPE09 S4)
RP03 PMEE=1(GPE09 S4) PMEE=0(GPE09 S0)
PEG0 (GPE09 S0)
PEGP (GPE09 S0)
So it looks like you should be woken up from S3 by receiving GPE 0x0D...
And in _L0D, it notifies the following devices:
Method (_L0D, 0, NotSerialized) // _Lxx: Level-Triggered GPE
{
Notify (\_SB.PCI0.XHC, 0x02)
Notify (\_SB.PCI0.EHC1, 0x02)
Notify (\_SB.PCI0.EHC2, 0x02)
Notify (\_SB.PCI0.HDEF, 0x02)
}
It seems only the following devices have something to do with S3 wakeup GPE:
EHC1, EHC2, XHC, HDEF
I don't know what the HDEF is.
Maybe you can:
"echo HDEF > /proc/acpi/wakeup" and try again.
It looks like there is also a BIOS configuration item related to HDEF wake
capability:
Method (_PRW, 0, NotSerialized) // _PRW: Power Resources for Wake
{
If (WKMD)
{
Return (Package (0x02)
{
0x0D,
Zero
})
}
Else
{
Return (Package (0x02)
{
0x0D,
Zero
})
}
}
Maybe your old behavior also relates to a BIOS configuration.
